To all whom it may concern:

Be it known that I, STEPHEN J. CL

a citizen of the United States, residing at Attleboro, county. f Bristol, State of Masin the Art of Making Eyeglass-Rims, of which the following is a specification.

This invention relates to eyeglass rims, and more specifically to rims of the celluloid type. One of the objects thereof is to provide a practical and-. -jjefl'ective art of making eyeglass rims, particularly of the above type. Other objects are to provide an art of the above nature which may be inexpensively and quicklyicarried on. Other objects will be in pointed out hereinafter.

The invention accordingly consists in the several steps and relation of such steps which will be exemplified in the manner hereinafter described, andthe scope of the application of which will be indicated in the following claims.

In, the accompanying drawing, illustrative of certam features of this mventlon,

Figures 1, 2, 3 and 4 are cross sectional views indicating various steps in the above art or process. 1

F igs. 5 and 6 are side elevations illustrating later steps in this art.

Fig. 7 is a side view of a rim.

Similar reference characters refer to.

similar parts throughout the several views of the drawing.

As conducive to a clearer understanding of this invention, it may be noted that it deals with the rims of eyeglasses, which term is broadly used "to comprehent'l any device for mounting lenses before the eye, irrespective of whether such device is mduntcd solely.oii the nose or is of the spectacle form. The invention moreover deals particularly with non-metallic or celluloid rims, the term celluloid also being broadly used -to denote any non-metallic substance suitable for with the art hereinafter described.

In the preferred method of carrying'on my art, the celluloid is forced into an elon gated form, similar to wire, and having a rounded cross section. This may be done by extruding the celluloid while the latter is in suitably plastic condition through dies of the proper shape. Preferably the cross section of the extruded material is not exactly round but is provided with a slight an Improvement part obvious and in part use 1n connection material is heated to the neighborhood of depression running lengthwise along one side as indicated at 1 in Fig. 1 of the drawing. \Vith the celluloid in proper condition for working, the groove or lengthwise. recessin the material or celluloid wire is preferably deepened to the form shown at 2 in Fig. 2 of the drawing. by milling or by other mechanical means. It is to be understood of course that many of the advantages of thisinventi'on maybe achieved either by milling the groove to its entire depth instead of first forming it by extrusion, or by extruding the material with a groove down to the form shown in Fig. 2

of the drawing.

In the preferred method of carrying on my art, the celluloid is hardened after'ex trusion and there is then inserted a metallic wire 3 which is fitted snugly at the bottom of the recess 2 and runs through the entire length of the celluloid wire 4. The material is then run through suitable rolls by which the celluloid is forced into a properly uniform cross section of the desired contour. This action, moreover, embeds the metallic wire'3 with the celluloid projecting thereover. as indicated-at 5, and locking the metal wire in position. It is to be understood that this rolling step is preferably employed even though no metallic wire is inserted. v

The eiitire material is then wound on a mandrel, being closely wound thereon and being disposed with the groove or recess 6 This may be done on the outer side, as indicated in Fig. 5

of the drawing. The ends being suitably secured in temporary position, the mandrel 7.-is then rotated and the material quickly andthoroughly polished along its entire exposed surface. The material is then removed and re-wound upon the mandrel with its outer or non-grooved side exposed. The material 15 again pollshed While n this condition and thus its entire surface, both in side and outsideis given a thorough and careful finish. While on the mandrel 7 in this last position, as indicated in Fig. 6, the a suitable degree, in one hundred degrees Fahrenheit, and thereupon permitted to cool, whereby it tends to set or retain the form which it then has. The entire coil of celluloid wire, out a considerable length and comprise a great number of turns, is then cut or slit which may extend throughlongitudinally of the mandrel, as indicated coils into a number of separate rims which are readily slipped off the end of themandrel.

In the final form of the rims shown in Fig. 7 of the drawing, each rim is a complete circle cut through at the point 9 and each-is of. uniform cross section throughout and accurately rolled to size. Moreover, a thorough polish or finish is given to the entire device, both inside and outside, and it possesses a high degree of mechanical strength and even without the embedded metallic wire, its method of manufacture tends to render it most homogeneous and tough. The metallic wire,'moreover, securely locked in position and embraced by the celluloid, gives it the highest degree of mechanical strengtln It is to be understood that if desired, the recess, as shown in Fig. 2 of the drawing, may be polished by the step indicated, in Fig. 5 before the metallic wire is inserted. I

- It will be seen that a rinr' formed as above not only possesses the above advantages but is' readily manipulated in use, as the lens may 'be quickly inserted by springing the rim apart at the cut 9. The rim tends to snap into closed position due largely to its method of manufacture, for it possesses a higher degree of elasticity than if merely cut from a blank. It will thus be seen that there is provided an art in which the .several'obor shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
